BACKGROUND/AIM: Gastric-type endocervical adenocarcinoma (GEA) is a rare but distinct histological type of gynecological malignancy. This study aimed to conduct a comprehensive analysis of the cytological features of GEA.
We reviewed 18 cytological samples obtained from 14 patients with GEA. All cytology slides were prepared using conventional smear and liquid-based preparations. We examined the differences between the cytological features of GEA and usual-type endocervical adenocarcinoma (UEA).
The cytological samples of GEA exhibited flat, honeycomb-like cellular sheets (p=0.035), vesicular nuclei (p=0.037) with prominent nucleoli (p=0.037), and vacuolated cytoplasm (p<0.001) more frequently than those of UEA, irrespective of the sampling site and preparation method. UEA showed three-dimensional cellular clusters (p<0.001), peripheral nuclear feathering (p<0.001), and nuclear hyperchromasia (p=0.014) more frequently than GEA.
GEA can be identified cytologically based on the presence of flat, honeycomb-like sheets of tumor cells possessing vesicular nuclei, prominent nucleoli, and abundant vacuolated cytoplasm.
背景/目的：胃型宫颈内膜腺癌（GEA）是一种罕见但具有独特组织学特征的妇科恶性肿瘤。本研究旨在对 GEA 的细胞学特征进行全面分析。
我们回顾了 14 例 GEA 患者的 18 例细胞学样本。所有细胞学涂片均采用传统涂片和液基制备方法制备。我们比较了 GEA 和普通型宫颈内膜腺癌（UEA）的细胞学特征。
GEA 的细胞学样本表现为扁平、蜂窝状的细胞片（p=0.035）、泡状核（p=0.037）伴明显核仁（p=0.037）和空泡状细胞质（p<0.001），比 UEA 更常见，与采样部位和制备方法无关。UEA 比 GEA 更常表现为三维细胞簇（p<0.001）、核周羽毛状（p<0.001）和核深染（p=0.014）。
基于存在扁平、蜂窝状的肿瘤细胞，具有泡状核、明显核仁及丰富空泡状细胞质，可对 GEA 进行细胞学诊断。
